CFTR: New insights into structure and function and implications for modulation by small molecules

Structural biology and functional studies are a powerful combination to elucidate fundamental knowledge about the cystic fibrosis transmembrane conductance regulator (CFTR). Here, we discuss the latest findings, including how clinically-approved drugs restore function to mutant CFTR, leading to better clinical outcomes for people with cystic fibrosis (CF). Despite the prospect of regulatory approval of a CFTR-targeting therapy for most CF mutations, strenuous efforts are still needed to fully comprehend CFTR structure-and-function for the development of better drugs to enable people with CF to live full and active lives.
